Specification of i 1 Application filed March is,

To all who/it it may "concern;

Be it known that I, lVAnREN E. ELLIS, a

liiltlZQD of the United States, residing at 'i-laverhill, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Bow-h Iaking Machines, of which the'following is a specifica- 'tion.

This invention, which relates to apparatus for making ornamental bows, is particularly intended to provide a simple and easilyoperated machine adapted to facilitate the assembling and securing together of the parts of bows constructed substantially asset forth in an appl'cation for U. S. Letters Patent filed by me on the 23rd day of August, 1911,

Serial No. 645,681. Such a bow, as constructed for attachment to a slipper or the like, is of the fiat type and comprises a these parts being secured together by la metallic plate or cli provided with prongs which. are passed through said parts and clenched, and my present invention includes various features of construction and arrangement whereby the bow parts above referred to are brought together in proper relation to one another and united to form a complete bow in such manner that but little skill or labor is required of the operator of the apparatus.

In particular, my apparatus includes a movable anvil which, during theformation of the bow, is located between the central band and the body portion ofthe bow, mechanismfor attachingthe metallic clip, the prongs of which are turned and clenched by the anvil, and folding devices which hold the ends of the central hand against the under side of the body portion of the bow during the attachment of the clip, together with various other parts and mechanisms hereinafter described, the complete machine as preferably constructed being illustrated in the"accompanying drawings, in which p b Figure 1 is a front elevation of the ma- L t er Fatent- Patented Feb. 9, 1915.

chine; Fig. 2 is a side elevation of the principal parts of the same, drawn to a larger scale; Fig. 3 is a sectional plan View ,on the line 33 in Fig. 2; Fig. 4 is a similarview of a portion of Fig. 3, showing a completed bow in the machine; Fig. 5 is an enlarged sectional view on the line 55 in Fig 2, showing the parts in position to drive the metallic, clip; Figs. 6 and 7 are front and side views, respectively, of the clip-driving mechanism in a modified form; and Fig. 8 shows another modified form of the clip-drivingmechanism.

The principal working parts of the maehine shown in the drawings are carried by a. table 1 which may conveniently stand upon a bench 1 having beneath it a treadle hereinafter referred to, whereby certain parts of the machine are operated. Said I.

table is provided on its upper face with a transversely-evtending groove 2 for the reception of folding and gripping devices hereinafter describedand with a recess 3 extending rearwardly from its front edge,

and crossing the groove 2, within which recess the bow is held while its parts are secured together. At the rear of the recess 3 the table 1 is provided with bearings 4: in

which is journaled a transverse]y-extending shaft 5 carrying a supporting head 6, to which head is detachably secured a forwardly-extending anvil 7 having the form of a thin flat plate or strip, and also an adjustable rod 8 serving as a gage and provided on its front edge with a spring clip 8 said rod being heldin any desired position of adjustment by a thumb screw 8*. The anvil 7 is thus capable of being raised and lowered with respect to the top of the table 1 and is so located that when lowered it is supported by the, table and extends across the groove 2, in which are located sliding plates adapted to be'operated by suitable means such as a disk 9 mounted beneath the table 1 on a verticalpivot 9 and having an operating handle 10, said disk being provided with two cam slots 11 and 12 which are diametrically opposite to each other and respectively receive pins 13 and 14: adjustably sev cured at their upper ends to the sliding plates above referred to. These plates, which are shown at 15 and 16 respectively, are provided at their inner ends with opposed folding and. gripping devices 17 and 18, which devices preferably consist of detachable plates and are recessed at their free edges, if necessary, to receive the clip-driving hammer hereinafter described.

The head 6, together with the anvil 7 and rod 8 which it carries, is normally held a short distance above the table 1 by means of a spring 19, shown as secured at its lower end to a downwardly-extending fixed rod and at its upper end to an arm 21 fixed to and extending rearwardly from the shaft 5, and said anvil is preferably provided on its under side with a thin metal strip 22 which is secured at its rear end to the anvil and extends forward in parallelism therewith at a short distance below the same, with its free end projecting somewhat beyond the free end of the anvil, by

Y which construction there is provided aslot 23 adapted to receive one of the bow parts as hereinafter explained.

The clip-attaching mechanism is carried by a standard 24 secured to and extending upward from the rear portion of the table 1 and thence forward to a point above but a little to one side of the anvil 7, where it is provided with vertical guides 25 in which a head 26 is adapted to slide. At its lower end the head 26 is provided with a laterally-extending portion 27 located over the anvil 7, and in said portion 27 is detachably secured, by means of a set screw 28, the shank 29 of a clip-driving hammer 30 which, in the construction shown in Figs. 2 and 5 has at its opposite sides a pair of vertically-sliding spring-pressed rods 31 carried by the part 27 and provided on their inner faces just above their lower ends with shallow recesses 32, while pins 33 passing through the reduced shanks of the rods 31 at their upper ends serve to limit their downward movement under the influence of their actuating springs 34. Vertical reciprocation of the head 26 is provided for by suitable means such as a link 37 connecting said head to a lever 38 which is fulcrumed at 39 on the standard 24 and is connected by another link 40 to a foot treadle 41 located beneath the bench 1 In using the machine above described the operator first inserts the central band 42 of a bow into the slot 23 and adjusts it therein until its rear edge is in contact with stops 45 and 46 secured to the parts 17 and 18 respectively, and its ends overlie the folding and gripping devices 17 and 18, .which devices at this time are separated to their full extent, corresponding to the position of the disk 9 and handle 10 shown in big. 3. The previously-folded body portion of the bow, shown at 43, with the attaching strip 44 applied to its under side, is then placed bottom side up on the top of the anvil 7, and its rear end is moved backward until it is arrested by the stop 8, where it is held by the spring clip 8% Said body portion is then pressed downward, carrying the anvil with it, until the plate 22 rests in the bottom of the recess 3, and thereupon the handle 10 is moved to the left from the position shown in Fig. 3, the cam slots 11 and 12 being so shaped that the resulting movement of the disk 9 causes the folding and gripping devices 17 and 18 to approach each other, with the result that the central band 42 is drawn tightly around the body portion 43 and has its ends folded down upon the attaching strip 44, where said ends are firmly held during the clipattaching operation. A soft-metal clip 36 having previously been placed against the bottom face of the hammer 30, where said clip is held by the location of its opposite edges in the recesses 32 and positioned by a stop plate 35 secured to the rear face of the hammer, the operator then exerts a quick downward pressure upon the treadle 41, whereby the head 26 is moved downward and the downwardly-extending prongs 36 of the clip 36 are driven by the hammer 30 through the subjacent parts of the bow until said prongs reach the anvil 7, which anvil is provided with grooves 47 adapted to turn the ends of said prongs and cause them to be clenched against the under side of the body portion of the bow behind the central band 42. The rods 31 yield under the force of the driving blow and release the clip 36, and the bow being thus completed the treadle 41 is released and the clipdriving mechanism is raised by means of a spring 47. The handle 10 is then thrown to the right, withdrawing the folding and gripping devices 17 and 18 from over the bow, and thereupon the spring 19 elevates the anvil 7 and the bow resting upon it, said anvil being located between the body portion of the bow and its central band. The bow is now free to be withdrawn from the anvil by sliding the bow forward, and thereupon the parts are left in position for a repetition of the operation.

The machine above described is adapted for making bows of various sizes and shapes within reasonable limits by reason of the fact that the anvil 7 and the folding and gripping devices 17 and 18 may be readily removed and replaced by other like parts of different sizes and contours, and to the same end the plates 15 and 16 are made adjustable with respect to their operating pins 13 and 14, and the stops 45 and 46 are adjustable on the parts 17 and 18, as shown. The clip-driving hammer 30 is also made detachable, so that it can be readily replaced by another hammer suitable for driving a different form or size of clip: For example, in case a narrow clip is to be employed the form of hammer shown in Figs. 6 and 7 ,may be utilized, this hammer being constructed substantially as already described,

except that the rods 31 are carried by the hammer 30 itself, instead of being carried by the lower portion 27 of thesliding head 26, and are located considerably nearer to gether than they are in the case of the hammer 30. In Fig. 8 still another form of driving hammer is shown, wherein the clip carrier 48 has downwardly-extending jaws 51 adapted to receive a clip 52 having the form of an ordinary staple, and is arranged to slide on the hammer 50 against the action of a spring 49, thus providing for a relati ve movement of the-hammer and clip carrier which will permit the former to pass downward between the prongs 51 to the lower ends of the same and thus'eflect the driving of the clip.

Various other modifications in the construction and arrangement of the various parts of the apparatus may be made with out departing from my invention, as will be evident.
